Answer:
The answer is letter B, absorb.
Explanation:
Heat travels through three different ways: radiation,conduction and convection.
Radiation- this happens when heat moves as energy waves (infrared waves) directly from its source to something.
Conduction- heat passes directly from one object to another through the touching of surfaces.
Convection- this occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas.
The transfer of heat in the situation above is an example of "thermal radiation." The campfire carries light energy through the fire. These consists of electromagnetic waves (most of these are infrared light). These waves (radiation) carry energy, which is then converted to heat once it hits another object that absorbs it. In the case above, once the hands absorbs the energy, it then warms up. This happened because the hands are placed near the campfire. Placing the hands near the campfire is important because air is a poor thermal conductor.
Thus, the answer above is letter B, absorb.
